Repeat interlock

WARNING: This page does not describe the selected car, but rather 7 other vehicles, including the 2017 BMW X3, 2016 BMW X3, 2015 BMW X3, 2014 BMW X3, and 2013 BMW X3. However, it is still accessible from the selected car via links, so may be relevant.

A repeat lock is provided for each motor to prevent the power window drive from overheating. The running time for the power-window motor is limited. The drive is switched off for a defined time. The repeat interlock permits at least five complete window movements (opening/closing). The last possible movement is always a closing process. If something becomes trapped, the anti-repeat circuit will not prevent opening. The anti-trap circuit always reverses the movement of the side window.
